Example 1 with TSComparator

use of org.apache.hadoop.hive.ql.optimizer.SharedWorkOptimizer.TSComparator in project hive by apache.

the class TestSharedWorkOptimizer method testTSCmpOrdersById.

@Test
public void testTSCmpOrdersById() {
    TableScanOperator ts1 = getTsOp();
    TableScanOperator ts2 = getTsOp();
    ArrayList<TableScanOperator> li1 = Lists.newArrayList(ts1, ts2);
    ArrayList<TableScanOperator> li2 = Lists.newArrayList(ts2, ts1);
    li1.sort(new TSComparator());
    li2.sort(new TSComparator());
    assertTrue(li1.get(0) == li2.get(0));
}

Example 2 with TSComparator
